View Full Version : Heater core flush, need coolant?

12-24-2010, 12:40 AM
Hello I plan on doing a flush on my 1998 audi a4 tomorrow but not sure if I will need any coolant or something?

Any other tips for the heater core flush too would be great, thank you.

I didn't read the link. But coolant would be a good idea to have for after, because when you flush it - there is coolant in there that you will flush out.

Just a nice thing to have to top it off after. Good luck! I think I am going after my heater core today too.
